When a pendulum reaches the end of its swing' the energy within the pendulum is of what sort?

Why does a pendulum in motion never swing to a greater height than it started?
This is a conservation of energy problem. When the pendulum starts out, it has gravitational potential energy; at the bottom of the swing, all of that has been converted to kinetic energy, and when it swings back up, back to gravitational potential energy (which is why speed is greatest at the bottom of the pendulum); in other words, there has to be the same amount of energy (PEgravitational = mass*gravity*height), where mass and gravity are constant.
Is in a pendulum at the top of a swing chemical energy?
No, it is not a chemical form of energy.
Why does a ideal pendulum swing back and forth indefinitely?
An ideal pendulum is one in which no air resistance or friction is present. Hence when set into motion it never loses energy to it's surrondings. So when released, and left to swing, the energy potential it had get's convertedinto kinetic energy and therefore the pendulum swings. When it reaches it's amplitude(Highest swing) the energy is converted back to potential, and as it falls back to kinetic. As it is "ideal" it never loses energy to heat/ friction. Therefore, the conversion of kinetic energy to potential etc etc will always be constant and it will never stop. Although in reality it is impossible to have an "ideal" pendulum, near ideal ones can be obtained by suspending the pendulum in a vacuum.
A swinging pendulum demonstrates which type of energy?
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
Describe the energy conversions that take place in the pendulum?
In a pendulum, the energy transformations involve potential energy being converted to kinetic energy as the pendulum swings back and forth. At the highest point of the swing, the pendulum has maximum potential energy, which is then converted to maximum kinetic energy at the lowest point of the swing. This process continues as the pendulum oscillates, with energy being continually converted between potential and kinetic forms.
What energy does pendulum transfer?
It converts gravitational potential energy (GPE) at the height of the swing to kinetic energy. This is then converted back to GPE. The process continues.
Does the pendulum had energy before you let go of the mass?
Yes, the pendulum has potential energy if you hold it at one end of its swing. If released, the pendulum starts to oscillate. During each cycle the potential energy is converted to kinetic energy and back again - twice.
A certain pendulum has a potential energy of 20 J when it is at the top of its swing. What is the kinetic energy?
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.

What happen to simple pendulum at lowest point of its swing?
At the low point of a swinging pendulum, the type of energy being demonstrated is maximum kinetic energy. It has zero potential energy at this point of the swing.
Is in a pendulum at the top of a swing chemical energy?
No, it is not a chemical form of energy.
What happens to the gravitational potential energy as the pendulum starts back up towards its highest point?
The pendulum's momentum or kinetic energy is converted to gravitational potential energy until all of the kinetic energy is converted. The pendulum stops.

A pendulum is designed to transfer potiential gravitational energy into?
A pendulum transfers potential gravitational energy (at the top of its swing) to kinetic energy (movement at the bottom of the swing) and then back again (at the top on the other side).
